Have you ever seen a 3D printer? They are amazing new machines that make 3D models from computer images, just like a normal printer would make a 2D paper copy of an image on your computer screen. You can see one in action here. But just as amazing is this Minecraft 3D printer. It’s so complicated and incredible. Check it out!

ItsJustJumby is a very clever person indeed. In the video he not only shows you how the 3D printer works, showing off his creeper model and a chicken, but shows you how he made it. 846 repeaters, 1124 hoppers, 9181 comparators, 10,539 pieces of redstone dust, and 20,103 command blocks are what this 3D printer is made of, and not one mod at all. This was totally made without any help, just Jumby’s incredible smart mind.

This is what the 3D printer looks like from the outside. Complicated!

To use the 3D printer, all you have to do is make your design on ten ‘levels’, each contained in one of ten chests. So if you wanted to make a pyramid like in Egypt, you would have to fill the first chest with materials, and then put fewer and fewer in each of the other boxes, until the tenth box only had one block for the very tip of the pyramid. Simple! Then you just hit the ‘print’ button, and the machine makes your model.

If you want to use the Minecraft 3D printer yourself, you can download the world it is in here. Then when you’ve made some amazing models, why not tweet us a picture of them?
